Communities not served by public sewers can face special water quality challenges because each household maintains its own septic system. A poorly-maintained system can fail, leaking sewage and threatening the health of our families and pets. WSU Mason County Extension and Mason County Public Health partner to provide training to help homeowners keep their systems functioning properly.

Septic workshops describe the basic components of septic systems and provide participants a chance to ask questions specific to their own needs. Attendees will learn what they can do on their own and when to call in the experts. All workshop attendees receive a coupon for a discount on septic system pumping or other maintenance service, a printed manual, and other informational materials.

How do Septic Systems Work?

 

A properly functioning septic system works like a miniature wastewater treatment plant:  bacteria, which need food (your waste) and air, do most of the work.

    1. Waste leaves the home, flowing into the septic tank, where solids settle out to the bottom and a scum of oils etc. forms on the surface.
    2. The liquid that remains flows out of the tank and into the drain field where it enters the soil through a series of perforated pipes.
    3. Helpful bacteria living in the soil and remove organic matter and potentially dangerous pathogens from the water before it percolates down into the water table.

How Do I Know If My Tank Needs To Be Pumped?

 

Solids build up at the bottom of your tank – over the course of 2-5 years – until they overflow. This can clog the pipes in your drain-field and cause major problems. Inspect your scum and sludge layers every year so you’re not caught by surprise.

Factors that impact sludge and scum buildup:

  1. Avoid using garbage disposals if you’ve got a septic system, they can speed up the accumulation of sludge.
  2. Throw away oils and greases, they will contribute to the scum layer.
  3. The number of people in the house. Growing family? you’ll need to pump your tank more often.
  4. The size of the tank. Tanks are typically 1000 gallons, but larger tanks can accommodate more waste.
